COMBINED KNIFE-BRICK BOX AND GRINDER.

SPECIFICATION forming part of Letters Patent No. 290,619, dated December 18, 1883.

Application filed October 15, 1883. (No model.)

To all whom it may concern:

Be it known that I, J OHN FRANCIS W001), of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Combined Knife- Brick Box and Grinder, of which the following is a full, clear, and exact description.

My invention consists of a-box for holding a knifebri ck, having a grater-bottom, onwhich the brick rests, and whereon the brick is always ready to be ground whenever the dust is wanted for scouring knives or any other object, the said bottom being located over the scouring-board, which is arranged to slide in the box under the bottom to receive the dust from the grater, and the box is mounted on rockers to enable the brick to be ground by rocking the box, to shift-the brick forward and back ward along the grater without handling the brick, to avoid getting the brick-dust on the hands, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cor responding parts in all the figures.

Figure 1 is a perspective view of my OOIllbined knife-brick box and grinder, with the cover of the box removed. Fig. 2 is a perspective view of the cover of the box, and Fig. 3 is a longitudinal sectional elevation of the box and grinder.

In any suitable box, a, I provide a gratingbottom, I), of any approved kind, adapted to grind a knife-brick, c, by shifting the brick along the grater, said grater being located above a chamber, d, in which the securingboard 6 may slide to be kept in place and to receive the brickdust falling through the grater. The box is provided with a sliding cover, f, to close in the brick, and at one end of the box is a cell, for holding the cork, chainois-skin, or other rubber to be used in the scouring process.

The brick may be shifted along the grater by hand for grinding off the dust as wanted; but I have arranged the box on rockers h, adapted to enable the box to be tilted forward and backward 011 the rockers, so that the brick will be made to slide forward and backward along the grater without touching the brick with the hands and without opening the box, thus making a much neater and cleaner device than if the brick were shoved by hand.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The brick-holding box a, having a graterbottom, 6, on which to grind the brick in its holding-box, said box a also having a scouring-board chamber, d, under "the grater-bottom, in which to place the board 6, for keeping and for receiving the dust from the grater, substantially as described.

2. The brick-holding box as, having a graterbottom, Z), on which to grind the brick in the box, and said box a being arranged on rock ers 71 to grind the brick by rocking the box,

substantially as described.
